You could also try dermatop, another cream for exzema he could get through your son’s medical doc instead of a derm doc. I have bad exzema but you wouldn’t know it because i use the Z bar twice a week and derma top and it makes my skin very smooth and soft and no flakes! Both things you need a perscription for. Also, if your son is shampooing too much, it could be causing more exzema. His scalp is probably getting too much soap and is reacting to it. Why does your son have a problem going to a derm doctor?
